Description
Technical field
The present invention relates to a kind of tensioner for rolling equipment, described tensioner is used for detecting
And the tension force in the intermediate stand section that adjustment bar or metallic plate are between two adjacent milling trains.
Background technology
Tensioner is known, the gold in the centre position for being placed between two adjacent milling trains
Belong to the equipment of hot rolling of plate, to detect and to regulate the bar in processing or metallic plate in intermediate stand section
Suffered tension force.
For the characteristic needed for giving product and reach high quality standard, monitoring bar or metallic plate
Tension force.
For example, as it is known that the characteristic of the profile of such as bar or plate and flatness depends on rolling whole
Maintain in the intermediate stand section that Cheng Zhong, particularly bar or plate are not directly supported with respect to the housing is suitable and constant
Tension value.
Known tensioner includes idler roller, and this idler roller is arranged on support and above and is arranged to two
Intermediate stand section between individual adjacent milling train contacts with bar or plate.
Idler roller can be driven to interact with bar or plate relative to the tension value of detection, thus
Act on the hydraulic motor being positioned on axis with support.
By being mounted close to force cell detector bar or the tension value of metallic plate of idler roller.
Alternately, position and/or pressure by reading hydraulic pressure order equipment can obtain bar or gold
Belong to the tension value of plate.
The exemplary shortcomings for the tensioner of rolling equipment of known type is that they require big peace
Dress space, the distance between one milling train of this appreciable impact and next milling train.
The shortcoming that former tensioner causes is that distance big between milling train causes bar or gold
Belonging to plate temperature during operation to decline, hot-rolled step is caused sizable defect by this, and can be
Require before follow-up rolling pass that operation is with recovery temperature.
That another causes therewith disadvantageously, with the same steps performed at higher temperature required by
Energy compare, need more multi-energy to come bar or metallic plate and perform identical processing.
Another is disadvantageously, produce between supporting contact element and making the movable part of its equipment moved
Raw sliding friction: this friction causes the poor efficiency in the action of premature abrasion and tensioner and not
Accurately.
JP62156013 describes a kind of tensioner with contact roller, and this contact roller is arranged in tool
Having the end of the axle of the hydraulic cylinder of the axis of less perpendicular, tension force detecting element is (in this concrete feelings
It is force cell under condition) it is arranged in and changes below hydraulic cylinder.
In this scheme, the combination of contact roller/hydraulic cylinder acts directly on force cell, may
It damages and causes the inaccuracy of measurement.
US 5,718,138 describe a kind of have contact roller tensioner, this contact roller be connected to
In the support arm association of the axle of hydraulic cylinder, in order to limit contact roller relative to bar or the placement of metallic plate
The desired height of plane.US 5,718,138 provides two kinds of methods of the tension force of detector bar, the first
Method uses the force cell substantially associated with tensioner, and second method uses liquid
The force value of cylinder pressure.
Accordingly, it would be desirable to the tensioner being used in rolling equipment is perfect, changing tensioner can overcome
At least one shortcoming of prior art.
Specifically, it is an object of the invention to obtain a kind of tensioner, this tensioner is pacified
It is contained in intermediate stand section, it is allowed to reduce between two adjacent milling trains than known tensioner
Distance, in order to make the bar in processing or metallic plate temperature reduce be reduced to minimum.
Therefore, it is an object of the invention to obtain compact and the heaviest a kind of tensioner.
Another object of the present invention is to obtain one accurately to cut reliable tensioner, and at this
Tensioner reduces the friction that movable part slip causes.
Another object of the present invention is the accessibility of the measuring cell improving tensioner, in order to enter
Row safeguards step.
Another object of the present invention relate to when the idler roller of tensioner weares and teares or is damaged without
The probability changed in the case of operation near measuring cell.
Another object of the present invention is that measuring cell is remotely located from bar or the district of metallic plate activity
Territory, reason is, owing to measuring cell is sensing element, so measuring cell should preferably be placed
In shielding vibration and the place of dust.
It is a further object of the invention to provide a kind of simple and economic tensioner.
The applicant has designed, tested and has implemented the present invention to overcome lacking of state of the art
Point, and obtain these and other objects and advantages.

Activate element 26 and detection device 17 can be according to the oval distal portions extended of idler roller 12
Advantageously arrange.
Use two detection devices 17 that detection can be made somewhat different than to control device 24 can process
And the tension value of the metal tape 15 reconciled, thus cause refining chasing after of tensioner 10 further
Trace back adjustment.
Obviously above-mentioned tensioning can be filled in the case of without departing from the technical field of the present invention and scope
Put 10 modify and/or set up.
Although it is also apparent that describe the present invention with reference to some instantiations, but this area skill
Art personnel should be obtained in that other equivalents of many of tensioner 10, so that right
All features of illustrating in requirement and therefore 10 be all within taking this in the protection domain limited.
